What Are the Major Applications of 1,4-Butanediol in Modern Industries? 1,4-Butanediol serves as a critical chemical intermediate, primarily produced through four industrial processes: Reppe (acetylene-based), Davy (maleic anhydride), butadiene, and propylene oxide routes. Its derivatives - including Tetrahydrofuran (THF) for spandex fibers and Polybutylene Terephthalate (PBT) for engineering plastics - are experiencing surging demand across multiple sectors. Environmental considerations are pushing manufacturers toward bio-based production methods, though traditional petrochemical routes still dominate about 80% of current capacity.
